The woman who got the crotch shot has no ties to Weiner and isn’t known to be part of his staff, Arnold said.

But she took her Twitter and Facebook pages down a few hours later, after her name and a possible picture began to circulate on blogs.

Weiner, who represents parts of Queens and Brooklyn, got a message about a week ago from Facebook alerting him that his password might have been tampered with, Arnold said.

But the warning was ignored, granting the hacker carte blanche to hijack Weiner’s online identity.

Weiner, 46, was well-known as a ladies’ man in Washington before he finally settled down with Hillary Rodham Clinton’s top aide, Huma Abedin. The couple was married last July in ceremony officiated by Bill Clinton.
